The structure and content of the medical subinternship: a national survey

To describe the educational and administrative structure and content of internal medicine subinternship (SI) programs at medical schools throughout the United States.

A cross-sectional mailed survey of internal medicine SI directors at U.S. medical schools.

Responses were received from 100 (80%) of 125 eligible programs. Seventy-five percent of schools require a SI for graduation; 26% of these schools require the completion of a medical SI. Nationally, about 75% of all medical students opt to complete a medical SI. Dedicated SI administrative committees exist at 46% of medical schools. A minority of programs provide students with explicit curricula (31%) or exclusive conference time (36%). In 44% of programs, subinterns are used by hospital departments of medicine as intern substitutes. Subinterns are responsible for sign-out and cross-coverage in about half of the programs, and all patient orders entered by subinterns require cosignature. Subintern evaluation criteria include attending evaluation (100%), resident evaluation (80%), case write-ups (27%), supervised clinical examination (20%), written examination (14%), and oral examination (3%).

Although most medical schools offer an SI in internal medicine and many require it, the experience often lacks clearly defined curricular goals and often does not provide medical students with house-staff-level responsibilities. In an effort to ease the transition from undergraduate to postgraduate training, further studies are needed to define which educational and structural components of the medicine SI should be developed and emphasized.
